* linux/powerpc/syscallent.h [384..386]: Add pkey_alloc,
pkey_free, and pkey_mprotect syscalls introduced by linux kernel
commits v4.16-rc1~93^2~70 and v4.16-rc1~93^2~69, respectively.
* linux/powerpc64/syscallent.h: Likewise.
* NEWS: Mention it.
There is no compat support in strace and there are no systems
within reach that would allow to test it.
* linux/ia64/arch_regs.c (IA64_PSR_IS, ia64_ia32mode): Remove.
* linux/ia64/get_error.c (get_error): Remove ia64_ia32mode branch.
* linux/ia64/get_scno.c (arch_get_scno): Likewise.
* linux/ia64/get_syscall_args.c (get_syscall_args): Likewise.
* linux/ia64/set_error.c (arch_set_error, arch_set_success): Likewise.
* linux/ia64/set_scno.c (arch_set_scno): Likewise.
While we are here, let's fix AArch64 by limiting scno shuffling
to compat personality only.
* syscall.c: Include shuffle_scno.c.
(shuffle_scno): Move it to a...
* linux/arm/shuffle_scno.c: New file.
* linux/aarch64/shuffle_scno.c: New file, define arm's shuffle_scno
as arm_shuffle_scno and call it only for personality 1.
* linux/shuffle_scno.c: New file, fallback trivial shuffle_scno
definition.
* Makefile.am (EXTRA_DIST): Add them.
Since this is where get_error gets the return value from in the compat case.
linux/x86_64/set_error.c (set_error, set_success): Update i386_regs.eax
if tracee is in compat personality.
From the very first commit when CRIS architecture support was introduced
and up to this comment that ends the agony of this non-functional code,
this support was incomplete and could never be compiled.
* Makefile.am (EXTRA_DIST): Remove linux/crisv*.
* clone.c: Remove CRISV* checks.
* configure.ac ($host_cpu == cris*): Remove.
* linux/crisv10: Remove.
* linux/crisv32: Likewise.
Fixes: v4.5.18-77-gea0e6e8 ("CRIS support by Hinko Kocevar ...")
Based on an analysis of arm_syscall in arch/arm/kernel/traps.c.
* linux/arm/syscallent.h ([ARM_FIRST_SHUFFLED_SYSCALL+1+2]): Update
argument number, add TM flag.
([ARM_FIRST_SHUFFLED_SYSCALL+1+1], [ARM_FIRST_SHUFFLED_SYSCALL+1+3],
[ARM_FIRST_SHUFFLED_SYSCALL+1+4], [ARM_FIRST_SHUFFLED_SYSCALL+1+5]):
Update argument number.
If the kernel contains commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3,
both PTRACE_PEEKDATA and process_vm_readv become unavailable when the
process dumpable flag is cleared, on ia64 this results to all syscall
arguments being unavailable.
Recognize this situation and do not treat it as get_syscall_args error
because the latter leaves the tracee in a ptrace stop.
This condition used to be triggered by prctl-dumpable test that caused
strace to hang indefinitely.
* linux/ia64/get_syscall_args.c (get_syscall_args): Do not bail out
if umove fails.
* tests/prctl-dumpable.c [__ia64__]: Skip the test.

[!HAVE_ARCH_SA_RESTORER && SA_RESTORER]: Define HAVE_SA_RESTORER to 1.
[!HAVE_ARCH_SA_RESTORER && !SA_RESTORER]: Define HAVE_SA_RESTORER to 0.

macro.
[!HAVE_ARCH_OLD_MMAP_PGOFF] (HAVE_ARCH_OLD_MMAP_PGOFF): Likewise.
* defs.h: Use #if instead of #ifdef to check HAVE_ARCH_OLD_MMAP.
* mem.c: Use #if instead of #ifdef to check HAVE_ARCH_OLD_MMAP
and HAVE_ARCH_OLD_MMAP_PGOFF
* pathtrace.c: Likewise.

arch-specific arch_defs_.h file followed by generic arch_defs_.h file.
